Embodiment Construction

[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Taking Intel X86 series microprocessor architecture as an example to illustrate the specific implementation of the present invention, all X86 series CPUs have a CPU instruction RDTSC, and the time count of computer startup can be obtained by using this RDTSC instruction.

[0036] The RDTSC instruction reads the time stamp counter, as shown in Table 1 below, by executing the RDTSC instruction, the current value of the time stamp counter of the CPU is loaded into the EDX:EAX register. The time stamp counter is contained in the 64-bit MSR register. The upper 32 bits of the MSR register are loaded into the EDX register and its lower 32 bits are loaded into the EAX register. The CPU increments the time stamp counter MSR once per clock cycle, and resets it to "0" when the CPU is reset.

Abstract

The invention discloses a method for recording real startup service life of a computer. The method comprises the following steps: during computer startup, transmitting an RDTSC (Read Time Stamp Counter) command after running to a specified code of a BIOS (Basic Input Output System); adding time count acquired by using the command with existing time count in a BISO ROM (Read Only Memory); when the computer attempts to enter a standby mode, or a hibernation mode or is turned off, executing a BISO ACPI (Advanced Configuration and Power Interface) code and transmitting SMI (Structure of Management Information); retransmitting a RDTSC command in an SMI processing producer; adding the time count acquired by using the retransmitted RDTSC command with the existing time count of the BIOS ROM. According to the method for recording real startup service life of the computer related to the invention, the real startup service life of the computer can be acquired.

Description

technical field [0001] The invention relates to a computer, in particular to a method for recording the real power-on service life of the computer. Background technique [0002] At present, there is no good way to obtain the real power-on life of the computer since it was shipped from the factory. The user guarantees the computer, but only uses the invoice time to determine whether the warranty period has been reached. For example, if the warranty period of a computer is set as one year, but there are actually two kinds of users: one is to use the computer every day, and the frequency of use is quite high; Lifespan is of course different. In the case of obtaining the real power-on service life of the computer, the maintenance cycle of the computer can be set: the warranty period of the user's computer is either the invoice time or the real power-on life, whichever comes first, even if the warranty period has reached . The automotive industry uses a similar method of calc...
